Alright, I have managed to understand a bit more... I think I know how to post comments and stuff like that now. =)

A bit about myself

I have played Tibia for about four years now I guess. It could be five, I'm not sure. At the moment I'm only playing on the game-world Inferna. My main character is called Arshalo, a level 105 ED at the moment.

Uhm... Things I have done:

-Found the formula for gaining experience by killing other players on PvP-enforced worlds...

-Found the formulas for calculating the damage/healing of all instant damage and healing spells.

-Found the formula for how to calculate how much damage your armor will be able of removing.

-Found the formula for how much damage Stone Skin Amulets, Silver Amulets, Dragon Necklaces, Protection Amulets, Elven Amulets, Strange Talismans and Might Rings removes

You can find most of what I have done on the Tibia.com forums, in the thread ID 1371675
